这是购物车的代码
用户在购物车中添加一些
**然后当用户进入购物车时，购物车会显示所有带有ID，名称和价格的物品**
最后总价
**我已经定义了一个while循环来总结价格并显示id名称等**
现在我想将项目ID发送到success.php，将数据库中的状态从“添加到购物车”更改为“已确认”

Answer 1

[已更新] 您可以将ID存储在一个变量中。

 <?php         
     $total=0;
     $ids = '';
     while ($row= mysqli_fetch_array($items_query_result)) {  
         $total+=$row['price'];
         if(strlen($ids)== 0){
            $ids = $row['id'];
         }else{
           $ids = ','.$row['id'];
         }
 ?>       
  <tr>

      <td><?php echo $row['id']  ?> </td>
      <td >  <?php echo $row['name'];   ?>
             <a href="cart-remove.php?id=<?php echo $row['id']; ?>" class='remove_item_link ' style="color:#e53939">
                 Remove 
             </a> 
      </td> 
      <td> Rs. <?php   echo $row['price']; } ?>  </td>
      <td> Rs. <?php echo $total;?>  
          <a href="success.php?id=<?php echo $ids;?>" class='btn btn-primary'>
            Confirm Order
          </a>
      </td>

然后在您的success.php中，您可以像这样展开$ids：

$ids = explode(",",$_GET['id'])); //with explode you can get splits the ids

for($i=0; $i<count($ids); $i++){
   $final_id = $ids[$i];
  //then here you can do the update sql query then the row id is the `final_id` in every loop you will update the database.
}

希望它会有所帮助！

<tbody>
<?php 
    $total=0;
    while ($row= mysqli_fetch_array($items_query_result)) {  
        $total+=$row['price'];  
        echo "<tr>";
        echo "<td>";
            echo $row['id'];
        echo "</td>";
        echo "<td>";
            echo $row['name'];
        echo '<a href="cart-remove.php?id='.$row['id'].'" class='remove_item_link ' style="color:#e53939">Remove </a>'; 
        echo "</td>";
        echo "<td>";
            echo "Rs ".$row['price'];
        echo "</td>";
        echo "<td>";
            echo "Rs ".$total;
            echo '<a href="success.php?id=" class='btn btn-primary'>Confirm Order</a>';
        echo "</td>";
        echo"</tr>";
     } ?>  
</tbody>

试试这个它会起作用，我已经纠正了你的迭代结束。通过它。
